Watching this process is both interesting and very, very impressive! I've been working a bit in something like this on my spare time -only using my mouse-... it's a paiiiiiiin for such a noob like me . A lot of respect for you Dolm , great work!

Okay so what I do when the flat colours are all done (it's a very important step) is that I put a new layer before the one with the lineart and start to paint over it with a soft brush.In the beginning it is all about adding volume and very rough textures, and eventually, when the painting gets more and more detailed, the lineart will almost disappear.Still, it is nice sometimes to keep it in certain parts of the painting for the contrast, when a sharp line is needed - like on the mouth here.

Great job. It looks so simple showing steps to completion. Everything fits in perfect. Sadly I'm never satisfied with my final lineart and adding flat colours. Would you be so kind to tell me how you make lineart in fotoshop or other graphic program (what size, brush, and so on) and how you add flat colours and go to step three when it looks like there are no lineart anymore?

Believe me, I know your pain. I quite hate this method of doing a nice lineart and then coloring it. I don't really know how to explain it, but it's just like you get locked within the lineart and can't escape it!

The lineart itself on Photoshop is very basic actually. I just use the first Photoshop brush and draw, and it can take hours if you want something clean. Just use a tablet and switch between brush (B) and eraser (E) all the time. What you can do too is work on a traditional rough with a pencil, then scan it and do your lineart like this : [link] - it will look a lot cleaner though, depends on what you like to work on.

The rest takes much more time to explain, and it definitly requires a graphic tablet. You have one?
